Notes to Table 1–14:
(1) For an explanation of terms used in Table 1–14, refer to “Glossary” on page 1–27.
(2) V_TT of transmitting device must track V_REF of the receiving device.
(3) Value shown refers to DC input reference voltage, V_REF(DC).
(4) Value shown refers to AC input reference voltage, V_REF(AC).
